Hi, thanks again for reply, in this days I will try.
I have another question, I have some problem set correct the z axis because I do not know what put in the microstep sight in setup.
I use this A4988 as driver and a normal 1.8 degrees motor, I have a thk linear module of 200 mm with a 1mm pich.
The problem is that I do not able to set the correct length high because the distance do not correspond to correct distance on every button in z axis calibration.
Can u explain step by step how I can set it correctly? I do no use endstop.
What is the value for microstep to put in setup?
Thanks for help

Hi to all,
I'm working on my lcd SLA printer and I want to use bandolo to drive it, 2/3 months ago I download an old version and all is ho correctly, now I upgrade my IV led under the lcd and use gpio 27 to drive it.
